From the cork oak to the stopper

All of our cork comes from the Alentejo and Algarve regions of Portugal and from Spain. We have operations there so that we can participate in the manufacturing process. Our business is based on the intrinsic quality of the raw materials. Working on site, our role is to approve the choice of cork before processing and confirm quality before loading.

Over the course of 25 years, we have developed processing and disinfecting methods that improve final quality significantly. We ask our partners to follow them:

Large-diameter production (25 mm)

Steam sterilization of the cork

Pre-washing the stoppers in a hydro-alcoholic solution

Peroxide-free organic wash

Disinfection using a limited amount of peroxide to maintain the cork’s natural appearance

Low-temperature storage

From cork to bottling

Our quality department is affiliated with a network of laboratories and analyses each batch of stoppers at reception to provide you the best possible product.

Sensory analysis,with 2,500 corks tested every week

Capillarity tests

Extraction force analysis

Mass density analysis

Humidity controls

Dimensional tests

Peroxide residue tests

Pressure tests for liquids and gases

More than 1,000 analysesof haloanisole and halophenol content conducted

Traceability system:
Batch identification and recording at every step

Each batch is then sorted at least twice, optically and manually, to identify defects and categorize the corks into groups of uniform appearance.And, finally:
